What the HTML Formatter does
Paste HTML and get it cleaned up to a consistent standard: normalized indentation, tidy attribute spacing, and structure that reads top to bottom. It's the everyday tidy-up for markup that's been edited by three people with three different habits.
Unlike a pure beautifier, the formatter also normalizes the small inconsistencies — mixed quote styles and ragged attribute lines — that creep into long-lived files.
Why the HTML Formatter is useful
Inconsistent HTML isn't broken, but it slows everyone down: reviews take longer, merges conflict more, and new contributors can't tell which style to follow. A formatting pass gives the whole file one voice.
It's also the fastest way to make inherited code approachable before you change it.
Also known as: html formatter, html beautifier, free html formatter, online html formatter, html formatter online free, html formatter tool, best html formatter tool.

Real-life use cases
Standardizing a team's templates
A lead formats the fifteen email templates three contractors wrote, so they all follow one style before the redesign starts.
Preparing code for review
A developer formats her component's markup so the reviewer sees the logic, not the indentation chaos.
Taking over a project
A freelancer formats the previous developer's templates on day one to map the site's structure.
Tips for the best results
- Format the whole file, not just your changes — partial formatting creates noisy diffs.
- Agree on settings with your team and stick to them; reformatting back and forth is worse than any single style.
- Run it before committing markup copied from browser dev tools, which arrives with odd spacing.
Conclusion
Paste the mixed-up markup, get one consistent style, and make the file yours.
Frequently asked questions
How is this different from the HTML Beautifier?
- Beautifying focuses on indentation; formatting also normalizes spacing and attribute presentation for a fully consistent result.
Will it change how the page renders?
- No. Formatting only touches whitespace and presentation of the code, never the structure or content.
Does it fix invalid HTML?
- No — it formats valid markup. A validator is the right tool for finding errors.
Can I use it on JSX or template files?
- It's built for plain HTML; JSX has different rules and needs a JS-aware formatter.
Is there a file size limit?
- Nothing imposed by us — the ceiling is whatever your machine can handle.
Does my markup leave this page?
- No — it all happens inside the tab.
